Khammam Police Commissioner Tafseer Iqbal said the police recovered a suicide note and have sent it for forensic analysis.

He said Saleem was apparently vexed with the family disputes as his father was a habitual drunkard and used to harass the family members.

“Preliminary inquiry shows he killed all the family members before committing suicide. We are doing further investigations,” the police chief said.

According to Saleem’s relatives, he woke up his family members around midnight and told them that somebody has done black magic to the family and hence they have to immediately go to the reservoir to perform some rituals to ward off its effects.

As they reached the reservoir, Saleem told his nephew Sheikh Lal that he forgot important items to do the rituals at home and sent him to fetch the same.
